Scan functions

This unit provides scan mode so that data can be scanned and transferred to a

connected computer or to e-mail via application software like the EPSON SMART

PANEL.

Simultaneous use of functions

Printer functions and scanner functions are independent and can therefore be

operated simultaneously from a connected computer.

Easy operation panel

The unit has a simple operation panel equipped with ten buttons*including power

button, LEDs that contain seven segment LED and provides basic functions only

for easy operation.

Note "* ": Only for CX4700/CX4800/DX4800/DX4850.(9 buttons for the model without card slot)

Exterior design

Use of a CIS scanner engine has enabled a more compact design.

Also, this unit has operation panel on the left side, which becomes more distinctive

but still easier to use.

1.3.2.3 Multi-slot Operations Overview

There is only one type of card that can be used to simultaneously access both

a connected computer and the direct printing function. The slots have assigned priority to determine which slot will be accessed first

when cards are inserted in several slots at once.

To select a card that has been inserted in a non-active slot, the card in the

active slot must first be removed.

Direct printing:

Only the image files in the active slot are valid and have assigned frame

numbers. The number of images will not change if a card is also inserted in

a non-selected slot.

Connection to computer (Windows):

Only one drive is displayed at a time as a removable disk and only the

card that is in the active slot can be accessed via the removable disk. A card

that has been inserted into a non-selected slot cannot be accessed.

Connection to computer (Macintosh):

Only the card in the active slot can be mounted on the desktop. A card that

has been inserted into a non-selected slot cannot be mounted on the desktop.

1.5.1.8 File Sorting Rules

This unit sorts photo data files based on the following prioritization rule.

File name is sorted in ASCII order as full path name.

NOTE: Sorting results are not guaranteed if two files have matching full-path file

names. (Matching full-path file names are not allowed under the DOS

specification.)

1.5.1.9 Rules for Acquisition of Date/Time Data

The following priorities are used to fetch date and time information from photo data

files.

1. Date/time data that complies with the standard format (Exif) for digitalcameras

2. Date/time data that complies with the DOS standard file system (file time

stamps)

3. Fixed values (01/01/1980, 00:00:00)

Note that the date/time data assigned to individual photo data files does not necessarily

match the date/time when the photo was actually taken. The photo date/time may be

modified due to the digital camera's calendar settings (presence/absence of functions,

incorrect date/time settings, etc.), processing of the photo data after the photo wastaken, or subsequent saving of data. In such cases, this unit performs the relevant

processing based on the most recently modified date/time data.

1.5.1.10 Number of Sheets which can be Printed in Total

Printing sum total number of sheets presupposes that it is possible to 999 sheets.

Moreover, the printing sum total number of sheets per sheet is possible to 99 sheets.

1.5.3 Index Sheet 30 thumbnail images are assigned per index sheet.

There are 3 marking areas for each thumbnail and you can set the number of

copies up to 3. Paper type and Paper size can be set from the operation panel.

The layout is fixed according to the paper type and it is not indicated on the sheet.

(Refer to 1.5.4 Layout and Paper Type, Paper Size (p.40))

Images are arranged in the Index sheet in ascending order (of image file number).

(Refer to 1.5.1.7 File Sorting (p.34)and 1.5.1.8 File Sorting Rules (p.35))

Index sheet will be printed from the last page, in descending order. (The sheet

containing first thumbnail comes top of printouts.)

The mode transition may occur from Print index sheet to Print from index

sheet when the Print index sheet completes successfully.

1.5.3.1 Rules for Scanning Index Sheets Index sheet scan range

Set index sheet in scanner

Place the side to be scanned face down relative to the scan bed, as described

below.

Align the corner of the sheet to the upper left origin point and make sure the

sheet is straight. Angled setting of the sheet is allowed as long as the sheet

remains within the scan bed's scan range (the maximum angle on the scan

bed is about 2.8).

The cover must be closed on the original to enable scanning. (This is to

prevent any shifting of the position marks while scanning).

Do not use paper that allows images to bleed through to the rear side.

(This is to prevent empty bubbles from being filled in by bleed-through.) Set scan area and original

Place the Index Sheet face down with its top edge aligned to the left edge of

the scan bed, and with the corner of the paper set to the original's top leftposition.

Basic specifications for scanning of index sheets

Scanning rules for index sheet

The existence of the following recognition factors is judged using the image

pattern matching. (Image is binary.)

When two or three marks of one image are filled, larger number will be used

for the number of copies. (ex. 1 and 3 are filled, number of copies is 3.)

When the optional ALL mark is filled, all images in the sheet will be

printed one by one regardless of each image mark is filled or not.

Index sheet error will be caused when any of image mark or ALL mark is

not filled.

Index sheet error will be caused when Left and right edges, Right top

EPSON and Block codes are not found correctly due to something like

smear.

1.5.6 Trimming Function

A trimming function is provided as a means of coordinating photo data with the types

of photo frames handled by this unit. This function is always activated so that printing

photo data is in shapes that fit these photo frames.

This function is described briefly below.The printed photo frame and the photo to be printed are matched in length along one

side and the photo is resized along the perpendicular side to fit the frame on that side.

Any part of the photo that does not fit within the photo frame is trimmed away (not

printed).

The ink absorbed from the Ink Cartridge goes through the filter and then is stored

temporarily in this tank called ink cavity until PZT is driven.

Figure 2-3. Printhead sectional drawing

2.2.2.1 Printing Process

This section explains the process which the Printheads of On-Demand inkjet printers

eject ink from each nozzle.

1. Normal state:When the printing signal is not output from the Main Board (C610 Main), or the

PZT drive voltage is not applied, the PZT does not change the shape. Therefore,

the PZT does not push the ink cavity. The ink pressure inside the ink cavity is kept

normal. (refer to Figure 2-4 (p.63): Normal state)

1. Current position temporary detection sequence determines if the carriage is in the

carriage lock position and releases the carriage if it is locked.

2. The carriage is moved to the left frame hit position and the carriage motor is

stopped.

3. The position that is specified steps right from the stopping place is defined as an

origin, and from that time, positional information is monitored by the linear

encoder.

If the positional information could not be gained during detecting carriage home

position due to the following causes, fatal error occurs.

Obstructions on the carriage path or other factors are giving too much

pressure on the CR motor. CR linear encoder failure, CR linear scale defect, etc.

In case that the PE Sensor cannot detect the top of a paper in the paper loading

sequence, the printer indicates the Paper Out error. If the PE Sensor cannot detect the

end of a paper in the paper feeding sequence, the printer indicates the Paper Jam

error. As for the details, refer to Chapter 3 TROUBLESHOOTING (p.87).

The Paper feeding mechanism consists of PF Motor, PF Roller, EJ Roller, PE Sensor,

PF Encoder and PF Scale etc. The Paper feeding mechanism feeds a paper loaded from

ASF Unit by using pairs of rollers.

1. One pair is the PF Roller and the Paper Guide Roller which is assembled in thePaper Guide Upper Unit. The drive of the PF Motor is transmitted to the Paper

Guide Roller through the PF Roller.

The PF Motor also controls the Pump Unit mechanism (including the Change Lever) as

well as the Paper loading/feeding mechanism. The drive of the PF Motor is always

transmitted to the Pump Unit. (And also, its drive is transmitted to the LD Roller

through the Clutch mechanism & the Change Lever.)

On this printer, the Pump Unit mechanism including the Change Lever plays a major

role expecting the ink eject operation. And, these operations control depending on the
